Abstract: System and method for energy efficient Ethernet with asymmetric traffic profiles. A low power mode such as a low power idle mode is typically leveraged when both direction of a link do not have data traffic to transmit. Where only one direction of a link has data traffic to transmit, a physical layer device can transition from a full duplex mode to a simplex mode to produce energy savings (e.g., disabling cancellation circuitry).

Abstract: A method and apparatus for transmit signal pulse shaping. Automotive vehicle manufacturers that incorporate electronic components into an automotive vehicle must consider emission requirements masks that can be dependent on particular geographic markets as well as the other electronic components contained within a particular automotive vehicle design. A physical layer device is provided that can be configured to operate in multiple emissions configurations using configurable parameters.
